Abstract

PURPOSE:To perform safely and continuously melting and solidifying of a plastic waste material, by a method wherein high-temperature and high-pressure air is sent to a melting furnace through a nozzle and a blow-off port of a side wall of a tubular screw shaft and the plastic waste material reduced through softening is solidified cylindrically by a molding cylinder. CONSTITUTION:Compressed air whose temperature has raised within a spiral heated air circulation sphere A is blown into a melting furnace 1 from a first air feed pipe 21 through nozzles 4, 4.... The compressed air sent into a hollow part 5a of a tubular screw shaft 5 from a second air circulation pipe 22 through a pipe 23 is blown out further into the melting furnace 1 through air blow-off ports 15, 15.... A plastic waste material is preheated by a heating trough 13, loaded within the melting furnace 1 through a waste material loading port 2 by a conveying screw 29 and sent into the lower part by a screw blade 6 while the same is being reduced through softening. The plastic waste material in a molten state is compressed in order, density is increased, solidified cylindrically by a molding cylinder 1c and extruded downward.
